Needs more LSx. I don't think people have been putting them in the S2k "for a while now". From what I've heard, I would guess that there are less than 10 LSx swapped S2K's on the road.
Good alternative to the LSx Miata as I would think that the longer wheel base might help a little.
However, I guess this is the next best thing, being that it is "keeping it Honda" and there is no Honda v8 on the horizon.
